Geologists use radioactive dating to I think it is to determine the absolute ages of rocks, but I'm not quite sure. If someone could explain the correct answer in simple enough terms for a thirteen year old to understand I'd be much obliged. The only explanations I've found so far are too hard to understand.
5 Key Principles of Relative Dating in Geology
Relative dating — Science Learning Hub
Radiometric dating calculates an age in years for geologic materials by measuring the presence of a short-life radioactive element, e. The term applies to all methods of age determination based on nuclear decay of naturally occurring radioactive isotopes. Bates and Jackson To determine the ages in years of Earth materials and the timing of geologic events such as exhumation and subduction, geologists utilize the process of radiometric decay. Geologists use these dates to further define the boundaries of the geologic periods shown on the geologic time scale. Radiometric decay occurs when the nucleus of a radioactive atom spontaneously transforms into an atomic nucleus of a different, more stable isotope.

Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50, years, and most rocks of interest are older than that. Carbon dating is used by archeologists to date trees, plants, and animal remains; as well as human artifacts made from wood and leather; because these items are generally younger than 50, years. Carbon is found in different forms in the environment — mainly in the stable form of carbon and the unstable form of carbon
